This document is not restricted to specific software and hardware
versions.

The outputs used in this document were tested on the Cisco 7000 router
with RP module.

The information in this document was created from the devices in a
specific lab environment. All of the devices used in this document started with
a cleared (default) configuration. If your network is live, make sure that you
understand the potential impact of any command.

The 7000 with RP has a boot image in ROM. This boot image is actually a
full Cisco IOS software image, unlike most other routers. It should always be
possible to boot it. If not, consider the possibility of a hardware failure.

In the event that you have another similar router, or at least one
other router which has a compatible PCMCIA Flash card filesystem (see PCMCIA Filesystem Compatibility
Matrix), you can also use that Flash card to recover the router.

If both routers are identical (same series), you can use the Flash
card from the other router to boot the one you want to recover. You can then
download a valid image the standard way (see
Software
Installation and Upgrade Procedures). Cisco 7000 routers run their Cisco
IOS software from dynamic RAM (DRAM), so you can remove a PCMCIA card while the
router is running.

If both routers are different, but have a compatible PCMCIA Flash
card filesystem, you can use the other router to load a Cisco IOS software
image into a Flash card, which you can then move to the router you are trying
to recover.
